Hicks: Whitney Houston's brother says he introduced her to drugs

Whitney Houston's brother told Oprah Winfrey on Monday that he introduced the singer to cocaine back in the 1980s.

Michael Houston sat down with his mother Cissy Houston and Winfrey on "Oprah's Next Chapter." He said he was the first person who did drugs with his sister, not her ex-husband Bobby Brown, who has had his own public battles with substance abuse over the years.

Michael said he feels extremely guilty for Whitney's death, but didn't understand what they were messing with. "You gotta understand at the time ... the 80s ... it was acceptable."

Right. Which is why absolutely no one went to prison for drugs during the 1980s.

His mother said "It's painful ... I feel responsible for what I let go so far."

Whitney died in Beverly Hills last February after a drug binge that included cocaine, Xanax and marijuana.
